educing new car emissions to 120 g CO 2 /km by 2012, as defined in the strategy, is notlikely to be achieved.Despite a low probability of achieving the 2012 target, the strategy, and the measures itincludes, has played an important role in reducing CO 2 emissions from light-dutyvehicles.Evolution of CO 2 emissions from new passenger cars by association are shown in Figure2 as well as the voluntary commitments undertaken by the European (ACEA), Japanese(JAMA) and Korean (KAMA) car manufacturer associations related to average new caremission targets of 140 g CO 2 /km by 2008/2009 (EU, 2010).The reduction of average CO 2 emissions from new cars can be achieved by means ofimprovements in vehicle motor technology (e.g. air-conditioning systems, pressuremonitoring systems…) as well as with the increased use of biofuels. The binding targetsfor Member States is to achieve a 10% share of renewable energy in the transport sectorby 2020 (Directive 2009/28/EC18).Figure 3. Evolution of CO 2 emissions from new passenger cars by association (adjustedfor changes in the test cycle procedure)Since the achievement of the EU objective of 120 g CO 2 /km in 2012 is not possible, newobjective implemented by Regulation (EC) No443/2009 is to achieve 130g CO 2 /km inthe period 2012-2015.A second target of 95 g CO 2 /km announced in the Strategy as a target for furtherconsideration is included for 2020. The modalities of reaching this target are to bedefined by 2013.Beside standards, fuel tax is a widely used policy instrument. However, the primaryreason for fuel tax is to increase governmental income and not to reduce CO 2 emissions.Fossil fuel prices were rather volatile and continuously increasing in the last decades.They may have a significant impact on travel demand and fuel intensity. The range offuel prices vary wide across analyzed countries mostly due to the different taxes.Actually, the largest part of fuel price in most of the countries is excise tax.The share of total tax (VAT and excise taxes) on gasoline is very different across theEU-countries ranging from 40% to 60% of the total gasoline price, see Figure 4.Currently, the highest tax on gasoline is in the Netherlands, Germany and Sweden. Thelowest tax on gasoline is in Cyprus.Risø International Energy Conference 2011 Proceedings Page 312

Gasoline prices in 2011 for EU-27 (Data source: Europe's Energy Portal,effective March 2, 2011)The share of tax in total diesel price in 2011 is shown in Figure 5. Currently, the highesttax on diesel fuel is in United Kingdom, 0.92 EUR per litre of diesel. The share of tax intotal diesel price is a little bit lower comparing to tax on gasoline. In EU the share of taxon diesel is in range from 36% to 57% of the total diesel price, see Figure 5.United KingdomSwedenSpainSloveniaSlovakiaRomaniaPortugalPolandNetherlandsMaltaLuxembourgLithuaniaLatviaItalyIrelandHungaryGreeceGermanyFranceFinlandEstoniaDenmarkCzech RepublicCyprusBulgariaBelgiumAustria0 0.2 0.4 0.6 0.8 1 1.2 1.4 1.6 1.8Price excl.
